I've had the same problem too. You cannot hide the subpanel borders with Labview 7 Evaluation or Full Development versions, only with the Professional version. However, you can of course Cheat ! The solution is to simply copy a subpanel with it's frame already hidden and paste it into your own application. You can find one such subpanel in the examples that came with Labview. The subpanels in Templates.vi do the trick and you can find it in: Labview 7.0\examples\general\controls\subpanel.llb
Hope this solves the problem.
